DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description of the preferred embodiment of the inventionis not intended to limit the invention to these preferred embodiments,but rather to enable any person skilled in the art to make and use thisinvention.

1. Device for Sexual Stimulation

As shown in FIGS. 1 and 2, a device 100 for sexual stimulation includes:an interaction module 110, a power module 120, and a control module 130.The interaction module 110 includes a housing 113, a female power port114 supported by the housing 113, and a first vibratory actuator 111 anda second vibratory actuator 112 coupled to the female power port 114,isolated from the housing 113, and supported by the housing 113. Thepower module 120 includes a rechargeable battery 121 and a male powerport 124 coupled to the battery 121. The male power port 124 isconfigurable between: a first configuration in which the male power port124 transiently couples to a female charge port of an external powersource to charge the battery 121 (shown in FIG. 9); and a secondconfiguration in which the male power port 124 transiently retains thepower module 120 against the interaction module 110 via the female powerport 114 of the interaction module 110 and communicates power to thevibratory actuators 111, 112, via the female power port 114, to generatehaptic vibratory stimulation. The control module 130 includes aplurality of input regions 131 and is configured to control vibratorymagnitude settings and vibratory pattern settings of the vibratoryactuators 111, 112 based upon inputs on the input regions 131.

In a variation of the device 100 for sexual stimulation, the interactionmodule 110 includes a housing 113 a female power port 114 supported bythe housing 113, and a haptic stimulation unit coupled to the femalepower port 114 and configured to stimulate soft tissue of a user. Inthis variation, the male power port 124 is operable between: a firstconfiguration in which the male power port 124 transiently couples to afemale charge port of an external power source to charge the battery121; and a second configuration in which the male power port 124transiently retains the power module 120 against the interaction module110 via the female power port 114 of the interaction module 110 andcommunicates power to the haptic stimulation unit, via the female powerport 114, to stimulate the sex organ. Furthermore, the control module130 includes a plurality of input regions and is configured to controlstimulation settings of the haptic stimulation unit based upon inputs onthe input regions 131. This variation of the device 100 thereforeimplements a haptic stimulation unit, which can include any one or moreof a vibratory actuator, a heating element, a cooling element, a linearor non-linear actuator, or any other suitable stimulatory unit, element,or component.

The device 100 preferably functions as a sex toy and can be manipulatedby a user to stimulate a sex organ of the user or a sex organ of apartner of the user. The device 100 may be used with the intent ofinitiating or aiding in orgasm. The device 100 includes an interactionmodule, configured to contact and stimulate a sex organ of a user, and apower module, configured to power the interaction module 110 and to beheld by the user when engaging the interaction module 110 against orinside a sex organ, as shown in FIG. 7. When the interaction module 110and the power module 120 are assembled in the second configuration,shown in FIG. 2, the interaction module 110 sources power from the powermodule 120 to generate a haptic stimulation suitable for sexualstimulation. The device 100 further enables the user to separate thepower module 120 from the interaction module 110 such that visual ortactile exposure to the interaction module 110, such as by the user andother observers, can be substantially limited while the device 100 isnot in use and while the battery 121 is recharged. Generally, the powermodule 120 and the interaction module 110 are preferably separable suchthat the portion of the device 100 that contacts or is inserted into asex organ (i.e. the interaction module 110) can be set aside or storedwhile a discreet portion of the device 100 (i.e. the power module 120)is recharged in plain view and through a common power source. Forexample, the male power port 124 of the power module 120 can plug into aUniversal Serial Bus (USB) port on a computer (shown in FIG. 9), astandard wall outlet, or a coaxial charging jack to charge the battery121 while the interaction module 110 is stored in a bedside table.Therefore, the particular configuration of the device 100 can minimizehandling or visual exposure of the interaction module 110, which can besubstantially more personal and more conspicuous than the power module120, when the device 100 is not in use. This particular configurationcan further permit the less conspicuous, more innocuous (e.g., lesspersonal) power module to be charged without attracting scrutiny fromobservers.

The interaction module 110 of the device 100 includes a housing 113, afemale power port 114 supported by the housing 113, and a first and asecond vibratory actuator 111, 112 coupled to the female power port 114,isolated from the housing 113, and supported by the housing 113. Theinteraction module 110 is preferably configured to stimulate an externalfemale sex organ, such at the clitoris, labia, vulva, perineum, anus,nipple, breast, or areola. The interaction module 110 can additionallyor alternatively be configured to stimulate a male sex organ, such asthe penis, scrotum, or anus. The interaction module 110 can additionallyor alternatively function to stimulate an internal sex organ, such asthe vagina, G-spot, prostate, rectum, or any other internal or externalportion of the body of a female or male user. The interaction module 110preferably generates vibratory stimulation through an electromechanicalactuator, such as an electric motor coupled to a counterweight, apiezoelectric transducer coupled to a mass, a charged diaphragm coupledto a mass, or any other linear or rotary actuator manipulating an(eccentric) mass to generate a vibration. Furthermore, the counterweightor mass can include a bladder system with a hydraulic or pneumaticcavity configured to fill and drain to adjust the vibratory output or“feel” of the vibratory actuator.

However, as described in the variation of the device 100 above, theinteraction module 110 can include any other element or component tostimulate a sex organ or soft tissue of the user in any other way. Forexample, the interaction module 110 can include a heating or coolingelement to heat or cool a portion of the body of the user, a set ofelectrodes to output electrical shocks or pulses to a portion of thebody of the user, lights or a display to output visual cues, or a smellmodule to provide olfactory sensations. The interaction module 110 canalso haptically stimulate the user with non-vibratory mechanical motion,such as by bending, twisting, curling, flexing, elongating, orinflating. Alternatively and as shown in FIGS. 11A and 11B, theinteraction module 110 can include a single vibratory actuary in. Theinteraction module 110 can therefore include any other suitableelectrical, electromechanical, or electrochemical component and/orlinkage to stimulate a sex organ or soft tissue of a user.

As shown in FIGS. 1 and 2, one example implementation of the device 100includes a vibratory actuator 111 that is an electromechanical motorwith an output shaft that supports a counterweight (i.e. eccentricmass). The motor is preferably a DC micromotor, though the motor canalternatively be a brushless motor, servomotor, stepper motor, or anyother suitable type of motor of any other size. As shown in FIGS. 1 and5, the vibratory actuator 111 can further include an enclosure thatshields the output shaft and counterweight when in motion. The motor ispreferably substantially circular in cross-section, and the enclosure ispreferably cylindrical with a shoulder proximal a closed end such thatthe motor can be slip-fit into the enclosure, output shaft first, withthe shoulder retaining the face of the motor proximal the output. A plug170 can then be pressed into the open end of the enclosure to capturethe motor. As shown in FIGS. 1 and 5, the assembly can further includean o-ring or other isolator between the plug 170 and the back face ofthe motor to absorb manufacturing tolerances of the assembly, such aslength or diameter tolerances of the enclosure, the plug 170, or themotor. As shown in FIG. 1, motor leads 160 preferably pass through abore in the plug 170, and the plug 170 preferably further includes afirst external circular groove adjacent a second external circulargroove, the first and second grooves configured to capture a firstisolator 140 and a second isolator 150, respectively. The first isolator140 preferably pivotably couples the motor to the housing 113, and thesecond isolator 150 preferably contacts a surface of the housing 113 todefine a soft pivot endstop. Generally, the first isolator 140preferably substantially constrains the vibratory actuator in threedegrees of translation and enables the vibratory actuator in at leasttwo degrees of rotation up to the compressible endstop defined by thesecond isolator 150. The first and second isolators 140, 150 arepreferably o-rings that engage the circular grooves in the plug 170,wherein the second isolator 150 is of an outer diameter less than theouter diameter of the first isolator 140, and wherein the secondisolator 150 is of a cross-sectional area less than the cross-sectionalarea of the first isolator 140. In this example implementation and asshown in FIG. 6, the housing 113 preferably includes a receptacle (e.g.,an internal bore with internal shoulder) that captures the plug 170 andisolators 140, 150 and enables the vibratory actuator 111 to pivot aboutthe first isolator 140, wherein the second isolator 150 limits maximumoff-axis deflection of the motor assembly (e.g., less than 10° offaxis). This soft coupling between the housing 113 and the vibratoryactuator 111 preferably isolates counterweight-induced vibrations fromthe housing 113, which can limit vibrations communicated to the powermodule 120 via the housing 113, the female power port 114, and the malepower port 124 when the device 100 is in use. Therefore, the softcoupling between the housing 113 and the vibratory actuator 111 canrender the device 100 more comfortable for the user by reducingvibrations transmitted from the vibratory actuator 111 into a handsupporting the power module 120 while in use.

However, features or elements of the foregoing example implementation ofthe vibratory actuator 111 can be incorporated into any other one ormore components. For example, the enclosure can incorporate the externalcircular grooves, thereby eliminating the need for the plug 170. Inanother example, the enclosure can define internal circular grooves thatcapture internal isolators (e.g., o-rings), wherein the isolators bothretain the motor within the enclosure and pivotably couple the enclosureto a protrusion extending from the housing 113. In yet another example,the enclosure can encompass the counterweight and only a portion of thelength of the motor, and the isolators can engage external circulargrooves machined or formed into the motor casing. In other exampleimplementations, the vibratory actuator 111 can couple to the housing113 via a ball-in-socket joint, a single rubber sleeve or gasketarranged between the housing 113 and the enclosure, a flex-orfluid-coupling, a four-bar linkage in which the housing 113 andenclosure each define a linkage, or any other suitable mechanicallinkage or coupling that mechanically couples the motor and/or theenclosure to the housing 113 with adequate vibration isolation.Furthermore, the motor, counterweight, output shaft, enclosure,isolators, or housing receptacle or protrusion that engages theisolators can be of any other form, dimension, geometry, or arrangement.

Housing material selection can affect transmission of vibrations fromthe vibratory actuators 111, 112 directly into the body of the userand/or into the power module 120. Generally, the housing 113 ispreferably a substantially rigid material, such as plastic or metal, tominimize low-frequency vibration transmission into the power module 120,and the housing 113 can be machined from billet, die cast, investmentcast, stamped, etched, injection molded, stamped, formed, ormanufactured according to any one or more techniques or methods. Forexample, the housing 113 can be diecast zinc, machined aluminum,injection molded high-density polyethylene (HDPE) or nylon, or stampedfrom stainless steel sheet. Alternatively, the housing 113 can be of amaterial that is substantially elastic or flexible, such as with aresonant frequency outside of an operating frequency range of thevibratory actuators 111, 112. For example, the housing 113 can be moldedrubber. However, the housing 113 can be any other suitable material andcan be manufactured via any other method or combination of methods.

The interaction module 110 preferably includes a pair ofelectromechanical vibratory actuators, each powered through a pair ofleads electrically coupled to a printed circuit board (PCB) coupled tothe female power port 114. The PCB can also support the female powerport 114 against the housing 113. The female power port 114 ispreferably a standard female USB socket including four pins. However,the female power port 114 can include a mini- or micro-USB port, acoaxial power jack, a Thunderbolt jack, an audio-type jack, Firewire,eSATA, HDMI, or any other suitable type or form of jack or digital port.In one variation of the device 100, the interaction module 110 includesa male or sexless jack or port rather than a female port, and the powermodule 120 includes a corresponding female or sexless jack or port. ThePCB preferably defines an electrical interface between the female powerport 114 and the vibratory actuator 111 leads, though the female powerport 114 can directly or indirectly interface with the motor leadsthrough any other component.

In one example implementation in which the female power port 114 is afemale USB socket, the PCB includes traces that communicate independentpower signals from the female power port 114 to the vibratory actuators111, 112. In this example implementation, a dedicated ground pin of thefemale power port 114 is preferably connected to one lead from each ofthe vibratory actuators 111, 112. A first standard digital pin of thefemale power port 114 is connected to a second lead of one vibratoryactuator, and a second standard digital pin of the female power port 114is connected to another lead of the second vibratory actuator 112 suchthat independent power signals can be independently communicated throughthe female power port 114 and over a common ground loop to independentlycontrol the vibratory actuators 111, 112. However, one or moreindependent power signals can be communicated to the vibratory actuators111, 112 via the female power port 114 and/or PCB to control thevibratory actuators 111, 112 in any other way.

In another example implementation in which the female power port 114 isa female USB socket, the PCB includes a driver 133 (e.g., a motordriver) for each vibratory actuator 111, 112, wherein each driver 133receives an independent digital control signal via a digital pin of thefemale power port 114 and distributes a power signal, in accordance withthe digital control signal, from a power pin of the female power port114 to a corresponding vibratory actuator. (In this and other exampleimplementations, the driver(s) 133 are preferably a portion of thecontrol module 130.) In this example implementation, the USB portincludes a first pin that is an analog power pin, a second pin that is aground pin, a third pin that is a first digital pin, and a fourth pinthat is a second digital pin, as shown in FIG. 10. In thisconfiguration, the drivers 133 and vibratory actuators 111, 112 arepreferably connected to the ground pin to define a common ground path,and the drivers 133 preferably siphon current from the power pin toenable driver operation. This configuration can reduce noise orinductive interference across analog and/or digital circuitry within theinteraction module, 110, power module 120, and/or control module 130,thus enabling uninterrupted operation of a processor 132, controller, ormemory arranged within any of the modules 110, 120, 130.

As shown in FIG. 4, the interaction module 110 preferably furtherincludes a polymer sleeve that sheaths a portion of the housing 113 andthe vibratory actuators 111, 112. The polymer sleeve 115 is preferably asilicone polymer that is molded around the housing 113 and the vibratoryactuators 111, 112 (or haptic stimulation units) in situ to define awaterproof, dustproof, and hermetic sheath over the portion of theinteraction module 110. Alternatively, the polymer sleeve 115 can bemolded separately and subsequently stretched or installed over thehousing 113 and vibratory actuators 111, 112 to define the waterproof,dustproof, and hermetic barrier around the interaction module 110. Thepolymer sleeve 115 preferably terminates proximal the female power port114, and at least one of the interaction and power modules 110, 120preferably includes a seal 180 proximal a respective power port suchthat the seal 180 and polymer sleeve can cooperate to define a completewaterproof, dustproof, and hermetic barrier around the interactionmodule 110 when the interaction and power modules are assembled. Forexample, the seal 180 can be an o-ring seal around the male power port124, as shown in FIG. 2, wherein the seal 180 engages the female powerport 114 to cooperate with the polymer sleeve 115 to define a barrierwith an Ingress Protection Rating of 25 or higher. Alternatively, theinteraction module 110 can include a metal parting band that supportsthe female power port 114 and engages a seal around the male power portto seal the device 100 in the second configuration, as show in FIG. 1.The polymer sleeve 115 preferably also defines a substantially smoothsurface that is food-safe, body-safe, hygienic, and cleanable withminimal internal or concave surfaces that can trap or hold dirt,bacteria, or fluid.

In one example implementation of the device 100 shown in FIGS. 1 and 2,the housing 113 supports the vibratory actuators 111, 112 with axessubstantially parallel and offset when not in use. When in operation orheld against a sex organ (as show in FIG. 7), the vibratory actuators111, 112 can deflect off axis, such as by pivoting about thehousing-actuator junction by up to several degrees. In this exampleimplementation, the polymer sleeve 115 preferably deflects with thevibratory actuators 111, 112 but does not substantially retardtransmission of vibrations from the vibratory actuators 111, 112 intothe body of the user. Furthermore, the vibratory actuators 111, 112 arepreferably powered by independent power signals and can thereforegenerate vibrations independently. Each vibratory actuator is thereforepreferably mechanically decoupled from the other vibratory actuator viathe isolators 140, 150 to define a distinct vibration source, and thepolymer sleeve 115 preferably sheaths but does not connect the free endsof the vibratory actuators 111, 112, as shown in FIGS. 1 and 2. Thisgeometry can enable the device 100 to output distinct,tactilely-discernible vibration patterns from multiple hapticstimulation sources. In one example, the device 100 can repetitivelypulse one vibratory actuator and then the other vibratory actuator. Inanother example, the device 100 can repetitively ramp the vibratorymotors up and down and out of phase, such as 45°, 90°, or 180° out ofphase. In yet another example, the device 100 can continuously drive onevibratory motor and pulse the other vibratory motor atpseudorandomly-selected times and power settings, such as every one tofive seconds for between one half and two seconds between 50% and 100%power.

The polymer sleeve 115 can further define interaction surfaces proximalthe vibratory actuators 111, 112. In one example implementation shown inFIG. 8, the polymer sleeve 115 includes ripples, studs, cilia-likestructures, or other tactilely-distinct features adjacent each vibratoryactuator. These features can be pattered uniformly around each vibratoryactuator or can be arranged on specific areas of the polymer sleeve 115.For example, the polymer sleeve 115 can define ripples on one side ofthe vibratory actuators 111, 112 and cilia-like structures on theopposite side of the vibratory actuators 111, 112 such that the user canflip the device 100 for application of different sensory stimulation. Inanother example implementation shown in FIGS. 1 and 2, the polymersleeve 115 defines a split loop over the housing 113 and vibratoryactuators, wherein the polymer material extends from each vibratoryactuator to the opposite vibrator actuator to define a pair of cusps. Inthis example implementation, the geometry of the polymer sleeve 115 ispreferably configured to accommodate the clitoris of a female user,either within the split loop or between the cusps. In this variation andas shown in shown in FIGS. 3A, 3B, and 3C, the polymer sleeve 115 canfurther include a chamfer of a first size on one side of the cusps and asurface of a different profile on the opposite side of the cusps suchthat a user can select a surface geometry that best accommodates theunique size, shape, or location of the user's clitoris. However, thepolymer sleeve 115 can be of any other geometry, include any otherstimulation feature, and define any other stimulation surface configuredto accommodate or stimulate any other sex organ or portion of the bodyof the user.

The interaction module 110 preferably includes a pair of vibratoryactuators 111, 112, though the interaction module 110 can include anyother number of vibratory actuators or haptic stimulation units of anyother type or form, supported by the housing 113 in any other way, andpowered in any other way to output any other suitable hapticstimulation. In example implementations, the interaction module 110 caninclude: one vibratory actuator; three (or more) vibratory actuatorscontrolled by a processor via a multiplexer or serial-in, parallel-out(SIPO) shift register electrically coupled to three (or more) motordrivers; a vibratory actuator and a heating element; or two vibratoryactuators and an infrared emitter. However, the interaction module 110can include any other suitable haptic stimulation unit, component, orelement. Furthermore, the interaction module 110 can define a geometryor include a haptic stimulation unit suitable for stimulation of aparticular sex organ. In example implementations shown in FIG. 8, theinteraction module 110 can include: a vibratory actuator adjacent ablunt (e.g., convex, narrowly protruding) surface suitable for clitoralstimulation (interaction module 110); a vibratory actuator within anelongated (e.g., phallic) member suitable for inter-vaginal stimulation(interaction module 100 b); or a vibratory actuator within adeeply-ribbed elongated member suitable for inter-rectal stimulation(interaction module 100 c). In another implementation, the interactionmodule 110 and power module 120 can each define semicircular sweptsections that assemble in the second configuration to define a ring,wherein the interaction module 110 includes a vibratory actuator suchthat the device 100 is suitable for penile stimulation. The interactionmodule 110 can further define a geometry suitable for stimulation ofmultiple sex organs simultaneously. For example and as shown in FIG. 8,an interaction module 110 d can include a vibratory actuator within anelongated member suitable for inter-vaginal stimulation and a secondvibratory actuator within a short curved member proximal one end of theelongated member and suitable for simultaneous clitoral stimulation.However, the interaction module 110 can include any other hapticstimulation unit in any other quantity or combination, and theinteraction module 110 can be of any other form or geometry suitable forstimulation of any other one or more portions of the body of the user.

The power module 120 of the device 100 includes the rechargeable battery121 and the male power port 124 coupled to the battery 121, wherein themale power port 124 is configurable between the first configuration andthe second configuration. As shown in FIGS. 2 and 9, in the firstconfiguration, the male power port 124 transiently couples to a femalecharge port of an external power source to charge the battery 121. Asshown in FIG. 1, in the second configuration, the male power port 124transiently retains the interaction module 110 via the female power port114 and communicates power to the vibratory actuators 111, 112, via thefemale power port 114, to generate haptic vibratory stimulation. Asdescribed above, the power module 120 is preferably separable from theinteraction module 110 such that the device 100 can be recharged whilethe interaction module 110, which can be substantially more personal andless discreet than the power module 120, is set aside. The battery 121can be any of a lithium-polymer, lithium-ion, lithium iron phosphate,nickel metal hydride, or any other suitable type of rechargeableelectric battery. The battery 121 preferably does not require removalfrom the power module 120 to be recharged and is instead preferablyrecharged by plugging the power module 120 into an external electricpower source, such as a computer (e.g., via a USB port, shown in FIG. 9)or a wall outlet.

However, the battery 121 can store any other type of energy in any otherform. For example, the battery 121 can store chemical energy in the formof hydrogen, wherein the male power port 124 sources hydrogen from anexternal source, the battery 121 stores the hydrogen, and an onboardgenerator or fuel cell converts the hydrogen into electrical energy topower the vibratory actuators 111, 112 or haptic stimulation units.Alternatively, the battery 121 can store hydraulic pressure, wherein themale power port 124 communicates hydraulic pressure, via the femalepower port 114, to the vibratory actuators to induce a vibration. Thebattery 121 (i.e. power storage module) can also store pneumaticpressure, vacuum, heat, steam, or any other electrical, chemical, ormechanical form of energy to subsequently power the interaction module110.

The power module 120 preferably further includes a charging circuit thatcontrols current and/or voltage signals across the battery leads as thebattery 121 is charged. In an example implementation in which thebattery 121 is a lithium-ion battery and the male power port 124 isconfigured to engage a USB port on a computer, the charging circuit canfirst deliver a near-constant amperage at increasing voltage to thebattery 121 until a desired battery voltage is reached, followed bydiminishing current at near-constant voltage until the battery 121reaches full charge saturation. If the power module 120 remainsconnected to the computer or other power source, the charging circuitcan further supply topping charge if the battery 121 discharges overtime (e.g., due to leakage currents in integrated circuits within thedevice 100). Furthermore, the charging circuit can communicate with aUSB port on a computer, via data (i.e. digital) pins on the male powerport 124, to source additional current from the port. For example,without active communication between the charge circuitry and thecomputer USB port, the power module 120 may only source 150 mA from thecomputer USB port. However, by actively communicating with the computerUSB port through the USB data pins, the charging circuit can request a500 mA source current from the computer USB port, which can enablefaster battery charging.

The power module 120 preferably further includes a power-conditioningcircuit. The power-conditioning circuit can include a voltage regulator,a buck circuit, a boost circuit, or other suitable electric circuit thattransforms the output of the battery 121 into signal of desired voltageor current. For example, the battery 121 can output a nominal 3.7V, andthe power-conditioning circuit can boost the battery output voltage to5.0V nominal to power a processor that controls the vibratory actuators111, 112. Furthermore, the power-conditioning circuit can regulate theoutput of the battery 121 from 3.7V nominal to a maximum of 2.0V toprevent damage to a motor or other component within a vibratory actuator111 or haptic stimulation unit. However, the power-conditioning circuitcan function in any other way to condition signals from the battery 121to power various components and systems within the device 100.Furthermore, the power-conditioning circuit and/or the charging circuitcan be arranged within the interaction module 110 rather than within thepower module 120.

As described above, the male power port 124 is configurable between afirst configuration and a second configuration, wherein the male powerport 124 communicates a power signal into the power module 120 (e.g.,into the battery 121) from an external source in the firstconfiguration, and wherein the male power port 124 communicates a powersignal from the battery 121 and into the interaction module 110 in thesecond configuration. The male power port 124 preferably includes a setof pins, tabs, conductive surfaces, etc. configured to engage a standardcharging jack to charge the battery 121 in the first configuration. Themale power port 124 is further configured to communicate power and/orcontrol signals to the interaction module 110 over at least some of thesame pins, tabs, surfaces, etc. to power and/or control the vibratoryactuators 111, 112 or haptic stimulation unit(s) in the secondconfiguration. The male power port 124 is preferably a standard male USBplug, though the male power port 124 can be a mini- or micro-USB port, acoaxial power jack, a Thunderbolt jack, an audio-type jack, or any othersuitable male or female plug, receptacle, or socket.

In the example implementation in which the male power port 124 is a maleUSB plug, the male power port 124 preferably transmits an analog currentsignal from a female USB socket of an external power source (e.g., acomputer, a wall adapter) via a dedicated standard ground pin and adedicated standard power pin (e.g., VCC pin). As described above, themale power port 124 can further communicate with the external powersource, via a digital send and digital receive pin (i.e. digital I/Opins), to source additional current from the external power source. Inone example implementation described above in which one driver 133 pervibratory actuator is arranged within the power module 120, the powermodule 120 (or control module 130) preferably decouples digitalcircuitry from the digital I/O pins and instead couples the drivers 133to the digital I/O pins. This configuration can enable communication ofanalog motor signals to the interaction module 110 to activate thevibratory actuators 111, 112 via the female power port 114, over acommon ground loop including the dedicated ground pin. In this exampleimplementation, digital I/O pins of the male power port 124 cantherefore send and receive digital signals and transmit analog signals.

In another example implementation described above in which the drivers133 are arranged within the interaction module 110, the male power port124 preferably couples power and ground terminals of the battery 121 orpower-conditioning circuit to the interaction module 110 via thededicated power and ground pins. The male power port 124 preferablyfurther communicates digital motor control signals from the processor132 to the drivers 133 via the digital I/O pins to activate thevibratory actuators 111, 112. In this example implementation thevibratory actuators 111, 112 are preferably powered by the drivers 133via a common power and ground loop. However, the male power port 124 cancommunicate digital and/or analog signals with the external power sourceand/or with the interaction module 110 in any other way.

As shown in FIG. 4, the power module 120 preferably further includes asecond housing 125 that defines a waterproof, dustproof, and hermeticboundary around the battery 121 in the second configuration (i.e. whenthe interaction module 110 and power module are assembled). Generally,the second housing 125 preferably cooperates with the seal 180 and thepolymer sleeve 115 to enclose and seal the power ports 114, 124, thevibratory actuators 111, 112 or haptic stimulation units, the battery121, and the control module 130 against fluid, dust, or other ingress inthe second configuration. The second housing 125 and the polymer sleeve115 can further enclose and seal a charge circuit, a power-conditioningcircuit, a processor 132, a driver 133, a memory module, and/or anycomponent within the device 100. The second housing 125 is preferably asubstantially rigid material, such as a metal or rigid plastic, thoughthe housing 113 can alternatively include a rigid substrate with a softsheath or coating, such as a polymer sleeve similar to the polymersleeve 115 of the interaction device. However, the exterior surface ofthe second housing 125 is preferably food-safe, body-safe, hygienic, andcleanable with minimal internal or concave surfaces that can trap orhold dirt, bacteria, or fluid. Furthermore, the outer cross-section ofthe second housing 125 proximal the male power port 124 is preferablysubstantially similar to the outer cross-section of the interactionmodule 110 proximal the female power port 114 such that the device 100appears substantially continuous across the power and interactionmodules in the second configuration (i.e. when assembled), as shown inFIG. 1.

In a variation of the second configuration, the interaction and powermodules 110, 120 are separated by an extension cable coupled at a firstend to the female power port 114 and on a second opposite end to themale power port 124. In this variation of the second configuration, thepower module 120 can power and/or control the interaction module 110substantially remotely via the extension cable, which can enable the useto stimulate a different sex organ, stimulate a sex organ in a differentway, and/or stimulate a sex organ more comfortable. The extension cablepreferably includes a seal at both the first end and the second end,wherein the seals cooperate with the interaction module 110 and thepower module 120 to define waterproof, dustproof, and hermetic barriersaround the modules 110, 120 in this variation of the secondconfiguration.

The control module 130 includes a plurality of input regions and isconfigured to control vibratory magnitude settings and vibratory patternsettings of the vibratory actuators 111, 112 based upon inputs on theinput regions 131. The control module 130 therefore preferably includesa button or other type of input region 131 configured to receive aninput from a user, the processor 132, and the driver(s) 133 (e.g., amotor driver, as described above).

The processor 132 is preferably a microprocessor, such as the ATmega328microcontroller by Atmel Corporation, configured to read analog pins ordigital bits set by the input regions 131 and further configured to setdigital output pins to control the vibratory actuators 111, 112 orhaptic stimulation unit(s). The processor 132 preferably controlsoperation of each vibratory actuator 111, 112 or a haptic stimulationunit by modulating the state of a digital output pin connected to amotor driver 133 (e.g., a MOSFET, an H-bridge), wherein the driver 133changes state according to the digital output pin to open and close ahigh-current path to the battery 121 (or power-conditioning circuit) todisable and enable the vibratory actuators 111, 112 (or hapticstimulation unit), respectively. The driver 133 therefore can functionto isolate the processor 132 from high-current signals. The processor132 preferably controls an output pin connected to the driver 133 viapulse-width modulation at a frequency less than a maximum switchingfrequency of the driver 133, thus enabling the processor 132 to pulsethe output pin at a duty cycle between 0% and 100% to vary the magnitudeof vibrations output by the vibratory actuators 111, 112 between fullstop and full speed. The processor 132 preferably sets the state of eachdigital output pin, connected to a vibratory actuator or hapticstimulation unit via a driver, independently such that the vibratoryactuators or haptic stimulation units can be independently controlled.However, the processor 132 can set the state of one digital output pinconnected to one driver electrically coupled to two or more vibratoryactuators or haptic stimulation units. Alternatively, the processor 132can set the state of one digital output pin connected to two drivers,each electrically coupled to one or more vibratory actuators or hapticstimulation units. Yet alternatively, the processor 132 can communicatewith a multiplexer via two or more digital output pins (e.g., one inputpin and one output pin) to control three or more vibratory actuators orhaptic stimulation units, via drivers, with a minimum of digital outputpins. However, the processor 132 can function in any other way tocontrol the vibratory actuators 111, 112 or haptic stimulation unit(s).

The processor 132 preferably stores vibratory patterns or other hapticstimulation patterns such that the user can cycle through the vibratorypatterns to access different sensory stimulations. For example, theprocessor 132 can store a steady vibration pattern, ramp patterns,pulsation patterns, pseudo-random pulsation or ramp patterns, or anycombinations thereof. The processor preferably stores the stimulationpatterns in the ROM and then transfers the patterns internally and onthe fly to the processor's RAM. The processor 132 can stored thepatterns in compressed format then decompress the patterns, which canenable the processor 132 to phase shift, time stretch, time shrink, ormodify the amplitude of the patterns.

The processor 132 preferably accesses a pre-loaded set of vibratorypatterns or other haptic stimulation patterns. However, the controlmodule 130 can download additional stimulation patterns, such as througha computer when the male power port 124 is connected thereto. In oneexample, the user can download stimulation patterns through a website ornative application hosted by a vibrator or sex toy manufacture, hostedon a forum including users of similar devices, or sent to the user by afriend, partner, or sex toy-related entity. Such predefined stimulationpatterns can be recommended to the user by others with similar devices,such as through a social network, a blog, a forum, or a website hostedby a sex toy-related entity. In another example, the user can create acustom stimulation pattern through a website or native applicationexecuting on a computer or mobile device, and the user can then transferthe custom pattern to the device 100 for subsequent use.

In one variation, the device 100 is configured to operate in a chargingmode in the first variation, a stimulation mode in the secondconfiguration, and a secondary function mode in either of the first andsecond configurations. Generally, the processor 132 preferablyidentifies the current configuration of the device 100 and (seamlessly)adjusts operation or current function accordingly. For example, in thesecondary function mode, the device 100 can function as a wired orwireless mass storage device (MSD) or a human interface device (HID) inwhich battery status or diagnostic information can be communicated tothe user. Furthermore, the user can access the secondary function modeto lock, password protect, change the order of patterns, or createpresets on the device 100, such as from an external USB host deviceexecuting supplied software.

The input regions 131 preferably include a set of buttons thatcommunicate with the processor 132 to set or modify operation of thedevice 100. Each button is preferably a mechanical momentary pushbuttoncoupled to a pull-down resistor and to a digital input pin of theprocessor 132. However, the input regions 131 can include a Hall effectswitch, an optical switch, a capacitive touch sensor, a resistive touchsensor, an acoustic touch sensor, or any other suitable type of tactileswitch or button. Furthermore, each input region 131 preferably providestactile feedback to the user, such as in the form of a click, when theinput region 131 is depressed or contacted by the user.

In one example implementation, the input regions 131 include a[POWER/MODE] button, a [DECREASE INTENSITY] button, and an [INCREASEINTENSITY] button. In this example implementation, the user can powerthe device 100 ON by depressing the [POWER/MODE] button, change avibratory pattern setting by depressing the [POWER/MODE] button,increase the intensity of vibration (or speed of a vibratory pattern) bydepressing the [INCREASE INTENSITY] button, decrease the intensity ofvibration (or speed of a vibratory pattern) by depressing the [DECREASEINTENSITY] button, and power the device 100 OFF by depressing andholding the [POWER/MODE] button.

In a similar example implementation, the input regions 131 can include a[POWER/MODE] button and an [INTENSITY] button, wherein the user canpower the device 100 ON by depressing the [POWER/MODE] button, cyclethrough vibratory pattern settings by depressing the [POWER/MODE], cyclethrough vibration intensity levels by depressing the [INTENSITY] button,and power the device 100 OFF by depressing both buttons simultaneously.However, the processor 132 can modify operation of the device 100according to any other single or combination of inputs at the inputregions 131.

Alternatively, the input region can include a dial, a slide, a series oftoggle switches, or other type of input region, button, or control. Forexample, the input regions 131 can include a dial, through which theuser can adjust the stimulation intensity, and a momentary mechanicalpushbutton, through which the user can power the device 100 ON and OFFand cycle through available modes (e.g., vibratory pattern settings).However, the input regions 131 of the control module 130 can be of anyother type, capture any other user input, and modify operation of thedevice 100 in any other way. Furthermore, the input regions 131 arepreferably backlit, such as with an LED arranged behind a translucentbutton. In this implementation, the backlights preferably depict thelevel of charge of the battery 121 when charging in the firstconfiguration. For example in the first configuration, the backlightscan blink slowly when the battery 121 has minimal charge and blinkfaster as the energy content of the battery 121 increases, wherein thebacklights show solid with the battery 121 is fully charged. Thisfunctionality is preferably controlled by the processor 132, and thebacklights can be any other suitable light-output device or lamparranged in any other way on the device 100.

The processor 132 is preferably further configured to enter a sleepstate, such as after a threshold period of time without use and/or givena user input to turn the device 100 OFF, in order to minimize currentdrain from the battery 121. In this implementation, a user input at aninput region 131 preferably trips an interrupt of the processor 132,which triggers the processor 132 to exit the sleep or OFF state. Whenpowering ON, the processor 132 can pulse a vibratory actuator or hapticstimulation unit in a pattern indicative of the charge on the battery121. For example, the processor 132 can pulse a vibratory actuator fivetimes when the battery 121 that has between 80 and 100% charge, fourtimes when the battery 121 that has 60 to 80% charge, three time whenthe battery 121 that has 40 to 60% charge, etc. Alternatively, when ON,the processor 132 can adjust the intensity of a backlight behind aninput region or the intensity level of any other lamp, LED, or outputmechanism on or in the device 100 to indicate battery level.

In one example implementation, the input regions 131 of the controlmodule 130 are arranged on or in the power module 120, as shown inFIG. 1. In this implementation, the processor 132 and the drivers 133are also arranged within the power module 120 such that the processor132 can substantially directly access input region outputs andsubstantially directly communicate with the drivers 133 (e.g., notthrough the power ports). In this variation, high-current drive signalsfor the vibratory actuators 111, 112 or haptic stimulation unit arepreferably communicated to the interaction module 110 through the powerports. Furthermore, in this example implementation, the input regions131 are preferably arranged on the power module 120 opposite the malepower port 124 (and opposite the interaction module 110) such that theinput regions 131 are substantially accessible to the user while holdingthe power module 120, which preferably transmits less vibration or otherhaptic stimulation into a hand of the user.

In another example implementation, the input regions 131 of the controlmodule 130 and the processor 132 are also arranged on or in the powermodule 120, and the drivers 133 are arranged within the interactionmodule 110. In this example implementation, the processor 132 preferablycommunicates with the drivers 133 over the power ports, as describedabove. Furthermore, in this example implementation, the input regions131 are preferably arranged on the power module 120 opposite the malepower port 124 (and opposite the interaction module 110) such that theinput regions 131 are substantially accessible to the user while holdingthe power module 120, as described above.

In yet another example implementation, the input regions 131 arearranged on or in the interaction module 110. In this exampleimplementation, the processor 132 is also preferably arranged within theinteraction module 110 and is powered by the battery 121 through thepower ports. The processor 132 can therefore also communicatesubstantially directly with the drivers 133 to control the vibrationactuators 111, 112 or the haptic stimulation unit(s). Alternatively, theprocessor 132 can be arranged within the power module 120 and accessinput region states through the power module 120, such as bycommunicating, via one-wire or I2C communication protocol, with aparallel-in, serial-out (PISO) shift register electrically coupled tothe input regions 131. However, the input regions 131, processor 132,and drivers 133 can be arranged in any other way within the device 100and communicate with one another over any other suitable connection orprotocol.

One variation of the device 100 further includes a memory module. Thememory module is preferably a solid state read/write hard drive or flashmemory configured to store digital data for future access and/orerasure. The memory module is preferably arranged within the powermodule 120 such that the male power port 124 can communicate datadigitally between the memory module and a connected external electronicdevice in the first configuration. In the implementation described abovein which the male power port 124 is a male USB plug including a groundpin, a power pin, and two digital output pins, the memory modulepreferably downloads data via the ground pin and a digital input pin andpreferably uploads data via the ground pin and a digital output pin.Therefore, in the first configuration, the power module 120 canadditionally function as a flash drive or memory stick. Furthermore, theprocessor 132 can access data stored on the memory module, such asvibratory patterns or user vibratory preferences, to control devicesettings when in use (i.e. in the second configuration). However, thememory module can be arranged in any other way within the device 100 andcan communicate with any other component internal or external the device100.

The memory module is preferably configured to store personal content ofthe user. Data stored on the memory module is preferably selected by theuser and pushed to the device 100 in the first configuration.Additionally or alternatively, the memory module can receive data orpersonal content wirelessly, such as from a smartphone or tablet via awireless communication module incorporated into the device 100. Forexample, the wireless communication module can access a smartphone, viaa Wi-Fi connection, to download personal video and images of the userengaging in sexual intercourse and other sexual acts, wherein the videoand images are stored on the memory module. The wireless communicationand memory modules can access and store such data in real time (i.e.while personal content is generated) and/or after the fact, such as whenthe user subsequently couples the device 100, either wireless orphysically, to an external electronic device. Similarly, the memorymodule can wirelessly broadcast personal content to an externalelectronic device. For example, the user can manipulate one or moreinput regions 131 to broadcast a video or image from the memory moduleto an external electronic device (e.g., a television, gaming console orreceiver coupled to a television, a smartphone, a tablet), and the usercan further manipulate one or more input regions 131 to play, pause,fast forward, rewind, and/or thumb through the video or image.Furthermore, the memory module can be locked or password protected tosecure stored data from unwanted or unwarranted access. Therefore, inthis variation, the device 100 can function not only as a sex toy byalso as a repository for personal and/or sex-related content such thatphysical and digital sexual paraphernalia can be embodied (e.g.,accessed) in a single device.

In a similar variation, the device 100 can further include an auditoryelement that outputs an audio signal. The auditory element is preferablya speaker arranged within the power module 120, and the auditory elementpreferably plays music, male or female sex noises, or other sounds toaugment the user's sexual experience. Auditory or sound data ispreferably stored on the memory module and access by the processor 132,which controls the auditory element through a speaker driver. However,the auditory element can be arranged in any other way within the device100, can be controlled in any other way, and can output any otherauditory signal.

In one variation of the device 100, the power module 120 furtherincludes a secondary vibratory actuator or haptic stimulation unit. Thesecondary vibratory actuator or haptic stimulation unit is alsopreferably powered by the battery 121, through a driver, and is alsopreferably controlled by the processor 132. In one exampleimplementation, the interaction module 110 includes a vibratory actuator111 within an elongated member suitable for inter-vaginal stimulation,and the power module 120 includes a secondary vibratory actuator withina short curved member suitable for clitoral stimulation, wherein thepower and interaction modules 1110, 120 assemble in the secondconfiguration to simultaneously stimulate both the G-spot and theclitoris of a female user. Alternatively, the power module 120 caninclude a heating element and can mechanically couple to the interactionmodule 110 that includes a vibratory actuator. However, the power module120 can include any other suitable secondary vibratory actuator orhaptic stimulation unit in any other quantity to cooperate with theinteraction module 110 to sexually stimulate the user.

As shown in FIG. 8, the power module 120 can be further configured tomechanically couple to interaction modules of various shapes,geometries, and configurations. The power module 120 can thereforeseparately power (and control) multiple interaction modules such thatthe user can customize the device 100 for a particular sexual experienceor for a particular sexual stimulation, use, or need. In an exampleimplementation, the device 100 can define a sexual stimulation kit withinterchangeable interaction modules, including a clitoral stimulationmodule 110, an inter-vaginal stimulation module 110 b, arectal-stimulation module 110 c, and a combination vaginal- andclitoral-stimulation module 110 d, such that the user can assemble thepower module 120 with different interaction modules suitable forstimulation of different sex organs. In this variation, the processor132 and drivers 133 are preferably arranged within the power module 120to reduce part count across the sexual stimulation kit. Each interactionmodule can be associated with different stimulation patterns, settings,or user preferences, and the processor 132 in the power module 120therefore preferably identifies each unique type of interaction modulesuch that each interaction module can be properly controlled. In oneexample implementation, the processor 132 reads a resistor value coupledto a pin of the female power port of an interaction module when thepower and interaction modules are assembled, wherein each type ofinteraction module includes a resistor of a value unique amongst the set(or kit) of interaction modules. In this example implementation, theresistor can be a component in a voltage divider defined in part by theinteraction module 110 and/or the power module 120, wherein an analoginput pin of the processor 132 is coupled to an output of the voltagedivider, and wherein the processor 132 implements an analog-to-digitalconverter to read the output of the voltage divider and identify thetype of connected interaction module 110. In another exampleimplementation, the processor 132 in the power module 120 receives, viathe power ports, a serial code from a secondary processor, timer, orother circuit within each interaction module when connected thereto,wherein the serial code is unique to each type of interaction module.However, the processor 132 in the power module 120 can identify the typeof a connected interaction module in any other way or through any otherhardware or software component. Furthermore and as described above, theprocessor 132 can substantially seamlessly modify operation or currentfunction of the device 100 according to a current configuration,attachment, mode, input, etc.

The vibratory actuator 200 preferably outputs vibrations proximal a freeend but limits transmission of vibrations into the support structure 213(e.g., the housing 113 of the interaction module 110 described above)that captures an opposite end of the vibratory actuator 200 via theisolators 240, 250. The vibratory actuator 200 is preferably suitable asa haptic stimulation unit within a sexual stimulation device, such asthe device 100 disclosed above. Because the vibratory actuator 200substantially minimizes vibratory transmission into the supportstructure 213, in comparison with a device with a substantially rigidmotor mount, a device incorporating the vibratory actuator 200 can bemore comfortable for a user holding the device, can be substantiallyquieter without sacrificing vibratory output or magnitude, and can besubstantially more efficient by focusing vibration to a particularregion of the device configured to stimulate a sex organ.

As shown in FIG. 5, the motor 210 includes an output shaft 215, and theoutput shaft 215 preferably extends from a single face of the motor 210.As described above, the motor 210 is preferably a DC micromotor, thoughthe motor 210 can alternatively be a stepper motor, a servomotor, or abrushless motor of any other suitable size. The motor 210 preferablyincludes a motor casing 217 that is circular in cross-section, thoughthe motor 210 or motor casing 217 can be of any other suitable geometry.

The counterweight 220 is coupled to the output shaft 215 and preferablyinduces a vibration when rotated by the motor 210. The counterweight 220is preferably pressed onto an end of the output shaft 215, but canalternatively be bonded, fastened, pinched, brazed, or otherwisemechanically coupled to the output shaft 215. The counterweight 220 ispreferably sized for the motor size, motor speed, and desired vibrationfrequency and/or magnitude. The counterweight 220 is preferably asubstantially dense material, such as iron or brass, though thecounterweight 220 can be any other suitable material.

As described above, the enclosure 230 encloses the counterweight 220 andthe output shaft 215. The enclosure 230 is preferably a spun, drawn,stamped, or machined metal enclosure 230 that slides over theoutput-side of the motor 210 to shield the output shaft 215 and thecounterweight 220. For example, the enclosure 230 can be stainlesssteel, cold-rolled steel with a zinc plating, aluminum, or brass.However, the enclosure 230 can be any other suitable material, such asplastic (e.g., HDPE, nylon), and can be manufactured via any othersuitable technique, such as injection molding. As shown in FIG. 6 anddescribed above, the enclosure 230 preferably includes an internalshoulder that engages the face of the motor 210 at the output side tolocate the motor 210 longitudinally within the enclosure 230. Theinternal profile of the enclosure 230 preferably accommodates the motor210 via a slip fit with minimal spacing (e.g., <0.001″ or 0.025 mm)between the internal wall of the enclosure 230 and the exterior surfaceof the motor casing 217, though the motor 210 can be installed in theenclosure 230 with any other suitable fit.

The first isolator 240 is coupled to the motor 210 opposite the outputshaft 215 and is configured to pivotably couple the motor 210 to themotor support structure 213. The second isolator 250 is coupled to themotor 210 adjacent the first isolator 240 and is configured to contact asurface of the motor support structure 213 to define the pivot endstop.As described above and shown in FIG. 6, the first and second isolatorspreferably cooperate to pivotably couple the motor 210 to the motorsupport structure 213, to isolate the support structure 213 fromvibrations induced by the vibratory actuator 200, and to limit maximumoff-axis deflection of the vibratory actuator 200 relative to thesupport structure 213. However, the isolators can alternativelyconstrain the vibratory actuator 200 in any other way, such as bylimiting off-axis deflection of the vibratory actuator 200 within asingle plane or by permitting the vibratory actuator 200 to translateaxially or cross-axially proximal the first or second isolators andrelative to the support structure 213.

The first isolator 240 is preferably an o-ring of a first outer diameterand a first cross-sectional area, and the second isolator 250 ispreferably an o-ring of a second outer diameter less than the firstouter diameter and a second cross-sectional area less than the firstcross-sectional area. As described above, the first and second isolatorsare preferably silicone o-rings of circular cross-section, such a Vitonor buna o-rings. However, the isolators 240, 250 can be of any othermaterial, form, or geometry.

As shown in FIGS. 5 and 6, the vibratory actuator 200 preferably furtherincludes a plug 270 pressed into the open end of the enclosure 230 toconstrain the motor 210. The plug 270 preferably includes a firstcircular recess or groove configured to receive the first isolator 240,wherein the first isolator 240 can further engage a recess or groove inthe support structure 213 to couple the vibratory actuator 200 to thesupport structure 213. The plug 270 preferably also includes a secondcircular recess proximal the first circular recess and configured toreceive the second isolator 250 such that the second isolator 250 candefine a compressible (or ‘soft’) endstop against a surface of thesupport structure 213 as the vibratory actuator 200 pivots about thefirst isolator 240, as shown in FIG. 6. The plug 270 preferably furtherincludes a through bore such that motor leads 260 can pass through thebore and electrically couple to a PCB, motor driver, or other suitableelectrical component, as described above. The plug 270 is preferably amachined aluminum plug 270 but can be any other suitable material andmanufactured in any other way. Furthermore, features of the plug 270,such as the circular recesses or grooves, can be incorporated into themotor casing 217 and/or into the enclosure 230 to enable similarfunctionality in variations of the vibratory actuator 200 that excludethe plug 270. However, the vibratory actuator 200 can include any othercomponent that functions in any other way or cooperates with any othercomponent of the vibratory actuator 200 to output vibrations suitable tofor a sexual stimulation device, such as the device 100 described above.
